Influence of pulping conditions on the pulp yield and fiber properties for pulping of spruce chips by deep eutectic solvent

open access: yesBiomass Conversion and Biorefinery, 2023
AbstractThe chemical pulping of wood chips using deep eutectic solvents (DES-pulping) has emerged as an alternative technology to conventional pulping in the paper industry, allowing the production of pulp in combination with the recovery of lignin and sugars for valorization.
